Determination of Melting Point/Melting Range for the Test Substance

 

Subsample ID	Instrument Gradient (°C/min)	Barometric Pressure (mm Hg)	Start of Melting Range °C (K)^1	End of Melting Range °C (K)^1	Melting Point °C (K)^1
523C-215-1   523C-215-2   523C-215-3	1.0   1.0   1.0	765.3   765.3   765.3	49.2 (322.4) 49.6 (322.8) 48.8 (322.0)	72.6 (345.8) 73.1 (346.3) 72.8 (346.0)	49.2 (322.4) 49.6 (322.8) 48.8 (322.0)
Overall Means: Standard Deviations: CV (%):		765.3 0.0 0.00	49.2 (322.4) 0.4 (0.4) 0.81 (0.12)	72.8 (346.0) 0.3 (0.3) 0.35 (0.07)	49.2 (322.4) 0.4 (0.4) 0.81 (0.12)
^1K (Kelvin) = °C + 273.15  Note: All calculations were performed using EXCEL 2010 in full precision mode.

 

Conclusions:

The test substance sample provided a mean melting point of 49.2 ± 0.4°C (322.4K) and a mean melting range from 49.2 ± 0.4°C (322.4K) to 72.8 ± 0.3°C (346.0K).

Executive summary:

Tests were performed to determine the melting and boiling point/range of the test substance. The study was performed based on procedures in the U.S. EPA Product Properties Test Guidelines, OPPTS 830.7200,Melting Point/Melting Range(1); OECD Guideline for the Testing of Chemicals, 102,Melting Point/Melting Range(2); U.S. EPA Product Properties Test Guidelines, OPPTS 830.7220,Boiling Point/Boiling Range(3); and OECD Guideline for the Testing of Chemicals, 103,Boiling Point(4). The experimental portion of the study was conducted between January 20 and 21, 2016. 

The test substance sample provided a mean melting point of 49.2 ± 0.4°C (322.4K) and a mean melting range from 49.2 ± 0.4°C (322.4K) to 72.8 ± 0.3°C (346.0K).

Specific details on test material used for the study:

Appearance: Light Borwn Solid
Storage Condition: Room Temperatire in the dark
Expiry date: September 2004

Key result

Melting / freezing pt.:

>= 71 - <= 73.5 °C

Decomposition:

no

Conclusions:

The melting range of the test substance was found to be 71.0 to 73.5 oC at normal atmospheric pressure

Executive summary:

The melting temperature was determined using the metal block method.

Dried test substance was pulverised to a fine powder and a small amount tightly packed into a capillary tube to a height of 3 mm. Following an initial estimation of melting point, the melting point apparatus was set at approximately 10°C below the expected melting temperature. The capillary tube was placed in the apparatus and heated at 1°C/minute until melting was complete. The procedure was performed in duplicate using a fresh sample on each occasion.

The melting range of the test substance was found to be 71.0 to 73.5°C.

Description of key information

Two studies were performed on the registered substance. The substance a mean melting range from 49.2 to 73.5 °C
